Specification of Letters Patent.

Application filed February 10, 1915.

To all whom it may concern:

Be it known that I, SPENCER H. PHELPS, a citizen of the United States, and a resident of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and Improved Colter, of which the following is a full, clear, and exact description. I

This invention relates to farm. implements and more particularly to an improved colter.

The primary object of the invention-is to provide a-novel support for a revolving colter blade adapted for attachment to 'a plow beam so that the blade may be adjusted at the proper angle so as to be set vertically or at an angle with respect to the ground, or adjusted up and down according to the depthof the furrow to be out, these adjustments being capable of accomplishment in a simple and effective manner.

With the above and other objects in view, the invention resides more particularly in the peculiarcombination and arrangement of parts to be hereinafter more fully described, illustrated and-claimed, it being also an object to provide a device which is simple in construction, durable and efficient indoperation and not likely to get out of or er.

Referenceis to be hadto the accompanying drawingsforming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views and in which- Figure 1 is a side elevation of the improved colter applied to a plow beam, a fragmentary portion of the latter being shown; Fig. 2 is an enlarged vertical secti onal view taken'on the line 22 of Fig. 1; Fig. 3 is a plan view of the structure shown in Fig. 1 with the colter blade and its yoke omitted.

As illustrated, the device includes a beam plate which is designed to fit one side of a plowbcam 11 which may be of either steel or wood, of any width or thickness. The beam. pl ate 10 is set at an. angle and clamped to the beam by bolts 12 adjusted through the extremities thereof and a beam plate 13 on the opposite side of the beam, the beam plate 10 having a rosette which. is clamped a guide plate 15 having a corresponding face-to look into the face of the beam.- plate 10 and to be angularly adthe bolt 18 as a hor zontal axis.

justed thereon by the coaction of the teeth and interveningnotches of said plates.

The numeral 16 designates a standard which is slotted vertically, as shown at 17, to be engaged by a clamping bolt. 18 which forms a swivel connection between the plates 10 and 15 and the standard, the guide plate 15 having a convex face 19 between which and the standard-a sliding block 20 is disposed. This block is provided with a concave face 21 opposing the convex face19 and opposite pairs of vertically spaced hori zontal guide lugs 22 project from the guide plate 15 to receive and guide the standard therebetween. A saddle washer 23 is fitted against the outer side of the standard with flanges to overlie the sides thereof so that when the nuts of the bolt 18 are clamped tight the standard will be held from swinging on a horizontal axis due to the clamping engagement of the 'roset-ted faces of the plates 10 and 15.

Atthe lower end the standard 16 is apertured and above said" aperture is provide with a segmental rosette or notched face 24, the aperture being designed to take a bolt 25 which pivotally supports a bracket 26, This bracket is provided with a segmental notched or rosetted face 27 coacting with the notches 24: above the pivot 25,.and the lower end of the bracket has a portion'28 which extends up in rear of the lower end of the standard. The bracket 26 is also provided with vertically spaced horizontal ears 36 between which yoke 29, in which a rolling steel colter blade 30 is journaled, through the medium of a vertical bearing sleeve 31, and a bolt 32 passing through said sleeve and ears.

According to the construction described the standard can be shifted to the right or left by loosening the bolt 18 and moving the block 20 up and down, it being understood that the plates 10 and 13 are set at the proper angle according to the width of the beam, are clamped together and then the guide plate 15 adjusted to bring the standard at the proper angle when pivoted on Furthermore, the yoke 29 may be adjusted on the pivot 25 due to the 'coacting notched or ro setted faces 24 and 27 so thatthe colter blade can be kept plumb, as shown in dotted lines in Fig. 2, or set at any desired angle is pivoted according to the furrow to be cut.

2 pleased The advantage of this construction is that the colter blade can, be set at any desired position with respect to theplow, allowing for any twisting or imperfect construction of the beam, while the slottingof the standard permits it tobe adjusted vertically for raising and lowering the colter blade. I

Having thus described my invention, What claim as new and desire to secure by Letters Patent is z- 1. In a colter, a clamp, a standard mounted to be adjusted vertically and angularly on a horizontal axis with respect thereto and a colter blade pivoted to the standard to be adjusted on a horizontal axis.

2. In a colter construction, a. clamp for attachment to a plow beam, a standard pivoted thereto for lateral. angular adjustment and a colter blade having a yoke pivoted to thestandard for lateral adjustment.

3.111 a colter construction, a clamp for attachment to a plow beam, a standard pivdted thereto for lateral angular adjustment and a colter blade having a yoke pivoted to the standard for lateral swinging move ment, said standard being adapted for vertical adjustniient with respect to the clamp.

4. A colterjadapted for attachment to plow beams or the like, comprising a beam plate having a rosette face, a second beam plate, clamping means connecting said plates,

aguide plate having a rosette face coopcrating with the rosette face of the first named beam plate and having a. convex face portion and guide members, a standard vertically slotted, a. clan'iping member forming a swivel connection between the first named beam plate,-guide plate and the standard.

and engaging the slot of the latterwhereby the standard may be vertically adjusted or swung on a horizontal pivot and held against movement, and a colter blade having a yoke pivoted to the standard for adjustment at right angles to the direction of extent of the plow beam. I

5. A colter adapted for attachment to plow beams or the like, comprising a beam plate having a rosette face, a second beam plate, clamping means connecting said plates, a guide plate having a rosette face coop crating with the rosette face of the first named beam plate and having a convex face portion and guide members, a standard vertically slotted, a clamping member forming a swivel connection between the first named beam plate, guide plate and the standard and engaging the slot of the latter whereby the standard may be vertically adjusted or swung on a horizontal pivot and held against movement, a block fitted between the convex face portion of the guide plate and the standard and having a concave face cooperating with said coiwex face whereby vertical adjustment of the block will swing the standard laterally with respect to the guide plate and beam, said standard having a seg mental notched portion at right angles to the rosette faces of the plates-aforesaid, a bracket pivoted to the standard and having a coacting notched face portion to be adjusted laterally with respect to the standard, a

yoke SlYiVOlGtl in the bracket and a colter blade journaled in the yoke.

(3. in a colter, a clamp, a standard vertically and angularly adjustably mounted on the clamp, and a pivoted colter carrying member laterally adjustable on the standard.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
